SEAL-PRESS CORD-TIGHTENER.'

Application filed October 20, 1915.

To all whom it may concern:

Be it known that I, VINFRED MUDGE BROOKS, a citizen of the United States of America, and a resident .of East Orange, in the State of New Jersey, have invented a new and useful Improvement in Seal-Press Gord-Tighteners, as hereinafter set forth.

The object of this invention is to provide a simple, positive and easily manipulated device for tightening the fastening cords, such as are used in connection with improved bag seals of the type set forth in my Patent No. 1,151,509, by drawing them through the seal and holding them at the desired tension until the seal is pressed and the cords locked.

The invention consists in an improved drum and clutch adapted to insure the positive gripping of the cords and other features as hereinafter more particularly set forth.

One sheet of drawings accompanies this specification as part thereof, in which like reference characters denote like parts throughout.

Figure 1 shows a perspective view of a seal press with the improved cord-tightener attachment, seal in place and the cords adjusted through the drum slot preliminary to sealing; Figs. 2 and 3 are top and front views respectively of the seal press head with the cord-tightener attachment; Fig. 4 is a sectional View of the drum clutch and guide on the line lei of Fig. 2 looking in the direction indicated by the arrow; Fig. 5 is an end view of the improved drum and clutch and Fig. 6 is a side view of the same.

Referring to the drawings, a represents the head part of a suitable seal press, I) the movable die, 0 the fixed die, d a bracket carried by said head part, c a bearing in said bracket, f a flanged drum mounted fixedly on a shaft 0' extending from one end thereof and carried in said bearing, 9 a lever handle fixedly connected with the other end of said shaft and adapted to turn said shaft and drum, h a diametrical slot in drum f extending approximately to the middle of said drum and adapted to receive the cords to be tightened, it a beveled entrance enlargement of said slot. 2' a seal, y the seal cords, Z a V-shaped guide integral with the bottom of the bracket or fixedly attached thereto and extending downwardly and out Specification of Letters Patent.

underthe drum, adapted to guide the sealing cords and retain same in said slot, m m flanges on the ends of the drum and n a clutch extending lengthwise of the drum between the flanges, adjacent to and parallel with the slot over which it partially extends on the side of the drum opposite the enlarged and beveled entrance to the slot, the same being the bottom side of the drum in its normal position. 0 0 represent pivot bearings for said clutch swiveling it between the flanges.

In operation the fastening cords are wrapped as usual about the neck of the bag to be sealed and drawn snug through the seal by hand. The seal is then placed between the dies of the press where it is firmly held by any suitable means preliminary to sealing, the free ends of the cords passing out over the bracket (Z. The cords are then slipped into the slot it through the enlarged and beveled entrance h which in the normal position of the press is inclined obliquely upward toward the dies and seal by the relative adjustment of the drum to the lever handle 9, the weight of the latter causing it to hang downward as shown in Fig. 1. The lever handle is then turned in a counter-clockwise direction and in the course of the first revolution the free ends of the cords are guided in and under the clutch n which is pressed into locking contact with them by the pressure of the coil formed over it by the cords as is shown in Fig. 4. The guide Z insures the proper alinement of the cords on the drum, guiding and retaining them in their proper positions in the slot. When the cords have been drawn to the desired tension, which can be readily estimated by the pressure on the lever handle, the seal is pressed and the operation is completed. The operation is extremely simple and efiective, the cords falling naturally into position in the beginning are automatically guided and clutched and are easily released at the conclusion. There is no slipping nor fraying of the cords as the locking grip of the clutch is positive, automatic and of strength increasing proportionately with the strain.

Having thus fully disclosed my invention, I claim 1. A seal press cord-tightener having in combination a flanged drum, means for rotatably mounting said drum on the seal press head, a diametrica'l slot in said drum extending from its free end adapted'to receiv'e the cords tobe tightened;- aclutch pivotally mounted between the drum flanges Copies of thisvpatent may be obtained for fi-vecents eaclr, by addxessingvt hei Cbmmissionenot Patents,

covering the under side of said slot on the side toward the press and a V-shaped guide fixedly mounted, under said drum, all substantially as hereinbefore specified. V
